Howdy from Texas! First post here, looking for help from more experienced bass players. A quick introduction might help you help me. I'm a professional BRASS player. My real (pays the mortgage) job is teaching in a public school, and I've got over 20 years teaching experience. I play on the side on virtually any and all brass instruments, having started as a trumpet player as a kid in the late 70s, and blossomed into a pro as a tuba player. I discovered my love for bass lines playing tuba, but...well, to put it simply, I'm a rock and roll musician at heart, but I'm stuck with the skill set of a jazz or classical musician. Nobody is going to hire a tuba player to be in their rock band. A couple of years ago, I was given a decent bass and amp to get started. The running joke was that I couldn't play it because I couldn't figure out where to put the mouthpiece... Fast forward to today, and I've learned a bit. Music theory is obviously not an issue whatsoever. Technique is where it's at for me, since my theory knowledge and brass knowledge are way beyond my skills. I want to keep building to a point where I can play my bass without thinking. I just GO THERE, like I can on a tuba. Whatever I think just happens because the instrument is just an extension of my ears/brain/heart. I've been using the Ed Friedland books 1-3 for a couple of years. I've bogged down a few times, started over, bogged down again, started over again...and it seems as if I'm finally getting to a point where the book's end is in sight. I won't move on until I OWN something, and I can almost say I own every concept in those books now. So, (finally) to my question: Where should I go next? I can put on my mp3 player and play along with some stuff (Eagles, various bands from the 70s-2000s), but I still have to skip on some stuff (Rush, RHCP, etc...) Thanks for taking the time to read this long first post, and thanks in advance for any advice you can give me.
